BAIL-FASTENING DEVICE.

Specification of Letters Patent.

Application filed. November 9, 191%. Serial No. 871,159

vide extremely simple yet highly efficient means for clamping the railsof a track upon the ties thereof.

In carrying out the above object, I employ certain novel features ofconstruction and combination herein described and claimed and shown inthe drawings wherein:

Figure 1 is a side elevation of a tie constructed in accordance with myinvention, showing a pair of rails resting thereon, in section; Fig. 2is an end view of one of the ties, and illustrating a side view of aportion of one rail; Fig. 3 is a top plan view of one of the ties andportions of a pair of rails thereon; Fig. 4 is a vertical transversesection as seen on the line 44 of Fig. 3; Fig. 5 is a detail transverse.section'as seen on the line 55 of Fig. 3; Fig. 6 is an inner end viewof one of the clamping blocks; Fig. 7 is a bottom plan view thereof,Fig. 8 is a top plan view of one of the-clamping blocks showing aslightly different form of construction, and Fig. 9 is an end view,similar to Fig 2, but showing the formation of the upper portion of thetie, when a set screw to be described, is forcibly tightened.

In the accompanying drawings, forming a part of this application, thenumeral 1 designates a transverse I beam which constitutes a railwaytie, '2 indicates a pair of longitudinal rails whose base flanges 3 restupon the upper flanges 4: of the I beam, and the numerals 5 and 6designate respectively inner and outer rail clamping blocks.

"The blocks5 and 6 are each of rectangular formation, as seen in thevarious figures of the drawings, and are provided with T slots 7 intheir lower portions, the shanks of said slots opening through thebottoms of the blocks and extending transversely across the same, asshown. These slots receive the upper portion or, inother words, theflanges 4 of the tie 1. In addition to the slots 7,

each of the clamping blocks is provided with a longitudinal groove 8 inits inner end, these grooves receiving the base flanges 3 of the rails.With the parts in this position, a set screw 9 is passed through theouter end portion of each of the clamping blocks and threaded intocontact with the I beam or tie, the lower or inner ends of these setscrews being pointed as seen at 10. These points are projected intorecesses in the tie, thereby preventing the clamping blocks fromslipping thereon.

In Fig. 9, I have shown the manner in which the upper flanges 4 of the Ibeam 1, may be dished or grooved, by excessive tightening of the setscrew 9, this operation being possible since the tightening of saidscrew draws the entire clamping block upwardly, thereby bending theflanges 4: upwardly beneath the rail 2. This becomes extremelyadvantageous, since the I beams 1 may be made of hardened steel, theupper corners of said beams then constituting biting edges forpreventing creeping of the rails 2, when the parts stand as seen in Fig.9. When the ties and rails are new and unworn, it is not necessary to tihten the screws 9 to the extent shown in Fig. 9, but when continualvibration has worn the rails and clamps. it is highly expedient to sotighten said screws, for the purpose set forth.

Although in most cases. but one screw 9 is sufficient for each clampingblock, three or more set screws may be employed as seen in Fig. 8. Thesescrews may be positioned as seen in this figure or in any otherappropriate manner.

From the foregoing description, taken in connection with theaccompanying drawings, it will be seen that an extremely simple devicehas been provided for carrying out the object of the invention, yet thatthe efiiciency of the device will not be impaired by such simplicity. 1

It will be readily understood that the clamps 5 and 6 may be adjustedinwardly and outwardly upon the beams 1 to provide tracks of eithernarrow or wide gage, these adjustments being also made when the upperportions of the beams 1 become worn after long use.

I claim:

The combination with an I beam whose upper corners are sharpened, a railresting on said beam, and fastening means abutting one side of the rail,of a rectangular clamping block resting on the beam and having atransverse slot in one end receiving the base-flange on the other sideof the rail, a pair of L-shaped flanges depending from the two sides ofthe block and having their horizontal portions contacting with the undersides of the horizontal flanges at the top of the I beam, and an uprightset screw threaded downwardly through said block and bearing against thetop of said I beam directly above its upright web, whereby tightening ofsaid screw may deflect said horizontal flanges upwardly to present theirsharpened upper corners for contact with the rail.

In testimony whereof I-have hereunto set my hand in presence of twosubscribing witnesses.
